6 ; Test case to show that -x86-pad-for-align causes binary differences in the
7 ; presence of debug locations. Inputs/pad-align-with-debug.s and
8 ; Inputs/pad-align-without-debug.s are equivalent, modulo a single .loc, which
9 ; cause the difference in the binary below. This should be fixed, before
10 ; x86-pad-for-align=true becomes the default.
